Good. > But, I'm a bit > confused.

The delete() function as defined below is recursive and will automatically go inside non-empty directories and empty them first. > $c_dir = "$DOCUMENT_ROOT/world/admin/backup2"; // current directory > > function delete($dir) { > if (file_exists($dir)) { > umask(0); > chmod($dir,0777); > if (is_dir($dir)) { > $handle = opendir($dir); > while($dirname = readdir($handle)) { > if ($dirname != "." && $dirname != "..") { > delete($dir."/".$dirname); > } > } > closedir($handle); > rmdir($dir); > } else { > unlink($dir); > } > } > } > > delete ($c_dir); To summarise -- there is no delete() function in php, the delete() function you're using is a user-defined function and as such will do whatever you can make it do. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* Garbage In -- Gospel Out. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
